_______________
 A. If the fault is identified by the crew observation:
 ACMS uploading is not possible.

 (1) Do a check for of the aircraft wiring between the ROUTING BOX-DATA LOADING (102TD) and DMU/FDIU (FDIMU) (10TV) (Ref. ASM 31-38/01):

 - A/32 (102TD) to pin AA/14G (10TV).

 (2) Do a check for of the aircraft wiring between the DMU/FDIU (FDIMU) (10TV) and the ROUTING BOX-DATA LOADING (102TD):

 (a) pin AB/11C, 11D (10TV) to the pin A/49, 16 (102TD).

 (b) pin AA/11C, 11D (10TV) to the pin B/17, 33 (102TD).

 (3) if the fault continues:

 - replace the ROUTING BOX-DATA LOADING (102TD) (Ref. AMM TASK 31-38-34-000-001) and (Ref. AMM TASK 31-38-34-400-001).
